I love the Dragon Age series of video games. The first, while flawed, is an outstanding game. The characters and setting are dark and rich. The second is definitely a flawed game, but it is still Dragon Age and I love it. I picked up the third game, Dragon Age Inquisition earlier this week and it's phenomenal.
The succubi of Dragon Age are called Desire Demons. The are spirits that dwell in the Fade and seek to bargain with mortals to experience the living world.
